When you select the lasso tool you should see a setting along the top left called "Feathering". If you have a number in there and the area you are trying to cut is small then what you are doing is basically cancelling out what you are selecting.
So get rid of any feathering numbers and keep it at zero. If the problem persists you can send it to me to fix.
